jquery 根据值更改字体大小？

我有 html:

<div class="arrow-inner arrow-first arrow-border">
 CAREER <strong>1.000</strong>
</div>

Jquery:

function battingAve1000(){
    var maxBatAve = "1.000";
    var batAve = $(".arrow-first strong").html();

    if(maxBatAve == batAve)
        $(".arrow-first strong").css('font-size', 20);
}

但它似乎不起作用？不知道为什么，似乎是对的......

}

But it doesn't seem to work? Not sure why, seems right...

这会起作用

function battingAve1000(){
var maxBatAve = "1.000";
var batAve = $(".arrow-first").find('strong').html();
console.log($(".arrow-first").find('strong').html())
if(maxBatAve == batAve)
    $(".arrow-first").find('strong').css('font-size', 20);}

但是可以检查 firefox 的 firebug 并了解 console.log() 以查看您的变量返回的内容。

实际上你的代码确实有效，你只是没有调用该函数？请参阅此http://jsfiddle.net/FWPd2/

This will work

function battingAve1000(){
var maxBatAve = "1.000";
var batAve = $(".arrow-first").find('strong').html();
console.log($(".arrow-first").find('strong').html())
if(maxBatAve == batAve)
    $(".arrow-first").find('strong').css('font-size', 20);}

But yes check out firebug for firefox and learn about console.log() to see what your vars are returning.

Actually your code does work, you just didn't call the function perhaps? See this http://jsfiddle.net/FWPd2/
